Greenheck, a leading manufacturer of air movement and control equipment, has announced an upgrade to its line of direct gas-fired make-up air units. These units now feature R-454B refrigerant, a hydrofluoroolefin (HFO) blend known for its lower global warming potential (GWP) compared to traditional hydrofluorocarbon (HFC) refrigerants. This change reflects Greenheck’s ongoing commitment to sustainability and providing environmentally responsible HVAC solutions.

The Shift to R-454B:

The HVAC industry is undergoing a transition away from high-GWP HFC refrigerants due to environmental regulations aimed at reducing greenhouse gas emissions. R-454B is a next-generation refrigerant with a significantly lower GWP than refrigerants like R-410A, which has been commonly used in many HVAC systems. This transition aligns with global efforts to mitigate climate change.

Key Benefits of R-454B:

Lower Global Warming Potential (GWP): R-454B has a GWP significantly lower than R-410A, reducing its environmental impact.
Improved Energy Efficiency: In some applications, R-454B can offer improved energy efficiency compared to older refrigerants.
Suitable for Various Applications: R-454B is suitable for a range of HVAC applications, including air conditioning and heat pumps.

Impact on Greenheck’s Make-Up Air Units:

The switch to R-454B in Greenheck’s direct gas-fired make-up air units means:

Reduced Environmental Footprint: Customers using these units will contribute to lower greenhouse gas emissions.
Compliance with Regulations: The change ensures compliance with evolving refrigerant regulations.
Continued Performance: Greenheck has engineered the units to maintain the same high level of performance and reliability with the new refrigerant.

Greenheck’s Commitment to Sustainability:

This upgrade is part of Greenheck’s broader commitment to sustainability and developing environmentally responsible products. The company continually strives to improve the energy efficiency and environmental performance of its HVAC solutions.
